Abstract (en)
[origin: EP2910794A1] An accumulator (1) includes a bellows (5) housed to freely expand and contract in a shell(2), a port part (6) having a pressure fluid inflow port (61) formed therein, and a self-sealing member (8) arranged on a tip portion of the bellows to face the port part, in which, when a pressure in the fluid chamber (4) is lower than a predetermined pressure relative to an air chamber (3), the self-sealing member is allowed to abut onto a seal area (SA) of the port part to block the pressure fluid inflow port. The self-sealing member includes a resilient member (82) arranged on a surface of a base material part (81), and an overhanging portion (83) formed on the resilient member and allowed to abut onto the seal area for sealing. The port part includes a seal face (63a) having the seal area formed thereon, and a projecting portion (64) arranged on a region other than the seal area on the seal face.
